Single-celled organisms with flagellar motion evolved several taxa of protists, some of which are not related but occupy an important place in this branch.
Flagellar travels rapidly with one or more whip-like threads, mostly feeding on smaller organisms, such as bacteria. However, unlike the variable amoeba, these flagellars have a fixed appearance, and the food they ingest flows into the "cell mouth" at the base of the flagellar. It is worth noting that some flagellars, such as eyeworms, have behavioral diversity, and they can be nutritionally plant-based or animal-based depending on the environment. When in bright conditions, these organisms can photosynthesis; in dark conditions, the chloroplasts, the cell tissues that absorb light, shrink and turn to prey on other organisms.

Most of the flagellar in this taxon lack general, respirable cellular structures and can only live in an environment where the animal's intestines are hypoxic. Many flagellar species specifically inhabit the abdominal cavity of insects, feeding on partially digested food in the abdominal cavity without causing harm to their hosts. There are also parasitic flagellar that can cause animals, including humans, to suffer from deadly diseases. One of the infamous flagellars, trypanosomiasis, is transmitted through insect bites and is responsible for sleeping sickness and kala-azar in the tropics.
Green-eyed worm – 50 μm
A common organism that causes blooms, this free-moving flagella has a flexible cell wall.
Slender eyeworm - small eyeworm - 35-55 μm
This eyeworm has a flagella that gathers together to form a gelatinous mucus.
Variable eyeworm - 50 μm
Variable eye worms are usually longer, a bit like bugs, and can change the shape of the body. Some species in the genus THJ//Eyeworm have flagellar, others do not.
Bahamas yahminium - 10 μm
The flagellate lives in sediments on the seafloor and feeds on detritus. One of its two flagella can be hidden in the feeding mouth.
Lambers Giardia – 9-21 μm
Lambert giardia, also known as Vibrio enteritidis, is an intestinal parasite that causes giardiasis. They are dormant cysts before parasitizing in the host and have a pair of nuclei.
Tropical Leishmania - 10-20 μm
The tropical leishmania is transmitted by the parasite, which causes cutaneous leishmaniasis. This skin disease infects more than 1 million people worldwide each year.
Termite flagellar - Trichomonas pyramidalis - 16 μm
Termite flagellar parasitizes the intestines of termites and helps termites digest wood chips. They have 4 flagellars at one end, with the 5th flagella swinging around the body.
Thread eyeworm - 125-130 μm
This green or brownish-yellow eyeworm of the genus Eyeworm has two flagellar hairs and a shell covered with rows of warts.
Trypanosoma brucei – 18-29 μm
Trypanosoma brucellosis causes sleep disease or trypanosomiasis and is transmitted in vertebrates through the bite of tsetse flies.

Most protists breathe aerobically in mitochondria, and the flagella in termite intestines lacks mitochondrial structures. Some scholars believe that these mitochondrial-deficient flagellars were the original protists. Some scholars believe that they are more advanced organisms, in the process of evolution, due to long-term living in an oxygen-deficient environment, resulting in the gradual disappearance of mitochondria in their cells.
